Medco has a double cylinder deadbolt that uses a captive key inside. It has
a handle on the inside key so it looks like a lever, but can be removed by
inserting the regular key into the outside cylinder and pulling on the
handle of the captive key. This way the inside key can be removed for extra
security when you are absent for a time, but other times it acts as a single
cylinder deadbolt.
